This invention relates to motor vehicle tion; The flange '19 inturn prevents edge-' 5 I wheels, and has for its object to provide an wise displacement in the same direction, of a improved construction for detachabl contire't onthedemountable rim.

I

Said enlargeof the form shown or any other suitable ment has a slot 33-opening through onefside form. On the felly is a fixed inner rim 13 and adapted to receive the inflating valve 0 having a lip or flange 14. adapted to prevent of, the tire t and permit the application and b0 erlgewise displacement in one direction of removal of the valve with the tire and the the demountable rim hereinafter describedy demounta le rim, the means for securing the a and a series of inwardly offset portions 15, demountable rim having provisions or bewhich enter recesses 16' (Fig. 7) formed in ing organized to permit the removal ofisaid the fellv. Said ofi'set portion and recesses ring in the direction required to remove the 1'10 55 prevent the fixedrimfrom turning on the valve' from the slot. Then the nuts 30 felly, the recesses forming transverse sock; and 31 are removed and the bolt 29is withdrawnfroni the clip 28, said clip is released opening interrupting its continuity, a fixed and the clamping ring 24 is free to be separated by an edgewise movement from .the

fixed clips 27 and removedv from the wheel,

the removable flange 20 and outer rim 18 be ing then removable sidewise. The fixed rim 13 ispreferably slightly tapered, one edge being of smaller diameter than the other, as shown by Figs. 3 and 4, the inner surfaces of the demountable rim 18 and removable flange 20 being correspondingly tapered/ Provision is thus made for a close fit of the rim'18 and flange 20 onthe fixed rim. The

reinforcing blocks 25 furnish solid metal bearings for the clamping ring 24, theclips 27 and 28, and thebolt which secures the detachable clip 28.

WVhile'I have shown the rim formed to engage a straight side tire, it is obvious that the rim may be adapted to engage tires otherwise formed.

Having described my invention, I claim: 1. The combination of a felly, a fixed rim having-a flange at one edge adapted to prevent edgewise displacement in one direction of another rim mounted thereon, a demountable rim fitted to the fixed rim and having tire-confining flanges, a clamping ring confiningthe demountable rim-on the fixedrim,

and rlng-securing means comprising fixed clips mounted on the felly and arranged to permit edgewise displacement of the clamping ring, and a removable clipdetachably secured to the felly and cooperating with the fixed clips in securing the ring, said ring,

I being removable edgewise when the removable clip is displaced.

2, The combination of a felly having an rim thereon having an inwardly projecting reinforcing block occupying said opening andslotted to receive a tire valve, the slot being open at one side of the felly, a demountable rim fitted to the fixed rim and provided with a tire valve extending through said slot, a clamping ring bearing-on one edge of the demountable rim and extending across the open end of said slot, and means for detachably securing said ring to the felly, the removal of the clamping ring permitting thev removalof the demountable rim from thefixed rim, and the removal of the valve from the slot.

3. The combination of a felly having reinforcing blocks on one of its sides, a fixed rim Wider than the felly and having a flange at one edge adapted to prevent edgewise displacement in one direction of another rim I PAUL D. HARROWERL .Witnesses: i
